Product Details
The Koni Sport Kit for the 2010-2013 Mazda Mazdaspeed3 pairs Koni's legendary adjustable yellow shocks with a set of Eibach Pro-Kit lowering springs — the gold-standard street performance suspension package. You get a 25–35 mm drop, sharper turn-in, and the ability to dial the rebound damping to your liking, all in one box.
Each Sport Yellow damper is externally adjustable for rebound, so you can run soft for daily comfort and stiffen for autocross or canyon runs. Eibach progressive-rate Pro-Kit springs preserve travel and ride quality while delivering the drop. This kit is the Koni catalog's most-recommended single upgrade for street-driven enthusiast cars.
